Application filed April 3,

To all whom it mag concern:

Be it known thatI, 'WEAVER F. Fnssnnn, a citizen of the United States,residing at Grove'City, county of Mercer, and State of Pennsylvania,have invented certain new and useful Improvements in Safety Devices, ofwhich the following is a specification.

My invention relates to guards for ma ohinery that is, to guardsespecially adapted for use in conjunction with machines having a numberof exposed moving parts such as? gear wheel s, fly wheels, beltsor otherrotatproperly attend to the same.

mg orreciprocating elements. The primary object of my invention is toprovide a cover or casing which may be arranged adjacent the exposedmoving parts of the machine to prevent persons from accidentally comingin contact with or getting parts. A further object of my invention is toprovide a device for thepurpose stat-ed. of such their clothingentangled in said moving construction that all portions of the machineshall be visible to the operator and that access may be readily had tothe guarded parts when necessary, incase of accident Other objects Willappear hereinafter. With these objects in view my invention consistsgenerally in a support adapted to be, secured in position: adjacent themachinery to be guarded, and a screen hingedly mounted on said supportwhereby the screen may 7 be readily swung out of the Way when it isdesired to have access to the guarded parts.

My invention-further consists in forming the hingedly mounted screen ofcoarse wire screening in order that all parts of the ma-- chine may bevisible to the operator and at the same time be of suiiicient strengthto serve its purpose as a guard.

My invention further consists in a hingedly mounted screen as stated incombination with a locking member comprising an arm adapted to besecured to the frame of the machine or adjacent thereto and providedwith a hook portion into which a portion of the frame. of the screen maybe sprung and retained.

My invention further consists in various details of construction andarrangement of Specification o1 Letters Patent.

parts aux n will be ma described hereinafter and particularly pointedout the claims.

My invention will be more readily understood by reference to theaccompanying drawings forming a part of this specification and in whichFigure 1 is a side elevation of a machine guard embodying my invention,in its pre- -ferred=-' form and illustrating .the same in position atthe end of a machine. jllig. 2

diagrammatically a machine to which the guard is applied and of which Aindicates the frame. portion of my invention and is illustrated merelyto give a clear idea of the arrangement and use of the guard, hencedetailed description thereof is unnecessary.

The guard proper comprises a frame 1 formed of a rod bent to the propershape and size and a screen 2 secured thereto. WVhile I have shown inthe drawings a screen of particular shape it is to befunderstood thatthe frame and screen ,are to be varied in both size and form tosuit theparticular machine or part to be guarded.

The arms 8 and 9 are preferably formedby bending the ends of the bar 7. 11 indicates hinges wherebythe guardis hingedly mounted on the support 7 A locking'member is providedcon1prising a bar 12 adapted to be secured to the frame of the machineor adjacent thereto and provided. near one end with a perforation 13 toreceive the securing means and at the other end with a U-shaped portionor hook 14 to receive the adjacent portion of E has full view of allportions of construction and efficient for the -prevent1ng persons orclothing from coming the frame l'when the guard is in closed position.From the construction of the guard it has sufficient resiliency topermitthe frame 1 tobe sprung into the hook 14. When the operator desires toobtain access to the guarded portions of the machine the frame isreadily lifted out of the hook of'the locking member and the screenswung upon the hinges 11 until out of the way v The guard of simplepurpose of above described is accidentally into contact with the movingmachine. Furthermore, While completely incasing the moving elements, theoperator his machine and may obtain quick access to thesame when desiredor necessary.

to said frame.

2. A guard for machinery comprising a screen consisting of an outerWall, top and side walls adapted to inclose the machinery to be guarded,a frame for said screen comprising a rod bent to shape and secured tothe inner edges of said top and side walls and the bottom edges of saidside walls and outer wall, said screen being formed of wire mesh, asupport, and a hinged connection' between said support and said frame,sub

stantially as described.

In testimony whereof'I have signed my name to this specification in thepresence of two subscribing Witnesses.
